The pipe does not accept any upgrades, and when you make loads of items (Think Omnifactory and 256 wires per craft) and it only extracts 4 items per operation it never finishes. I had to wait 30 minutes for 1 craft. Is it possible to add support for extraction speed, item action speed or item stack upgrades?

Heh, make sure you get the latest version
Since you should able to put those upgrade to the pipe
